LAMP.

Specification of Letters Patent.

Patented Apr. 18, 1911.

Application filed August 21, 1909. Serial No. 514,067.

To all whom it may concern:

Be it known that I, WILLIAM C. COLEMAN, a citizen of the United States,residing at Wichita, in the county of Sedgwick and State of Kansas, haveinvented certain new and useful Improvements in Lamps, of which thefollowing is a specification.

The present invention relates to lamps for burning a gaseous mixture ofhydrocarbon, alcohol, or similar fluid and air.

The object is to provide a very simple structure that will be compactlyhoused within the ordinary mantle-containing globe.

The preferred form of construction is shown in the accompanyingdrawings, wherein Figure 1 is a side elevation of the same, with theglobe and globe support illustrated in section. Fig. 2 is a verticalsectional view therethrough.

Similar reference numerals designate corresponding parts in all thefigures of the drawings.

In this invention, as disclosed, a vertical downwardly extendingvaporizing tube 3 is provided, to the lower end of which is connected avalve casing 4: that is disposed in line therewith, and has anoutstanding tubular portion 5, from which projects the rotary valve stem6. The valve seat 7 is arranged horizontally in the casing, and acombined cut-off and regulating valve 8 cooperates with the seat, and iscarried by the stem 6.

Depending from the valve casing, and suitably secured thereto in linewith the vaporizing tube 3, is a vapor feeding nozzle 9 that isdetachably located in the enlarged head 10 of a combined air andvapor-conducting pipe 11 disposed vertically in line with the vaporizingtube 3. The head 10 of this pipe 11 has an ofltset air inlet elbow 12.The pipe 11 is completely surrounded by a mixing chamber 13 supportedfrom the head 10, and having at its upper end opposite outstanding anddepending mantle supports 14:.

With this structure, the liquid fuel introduced into the upper end ofthe vaporizing tube 3 is delivered downwardly and vaporized in saidtube. Passing the valve 8, it is discharged through the nozzle 9downwardly into the pipe 11, which also carries air with it into themixing chamber. The mixture is returned upwardly through said chamber tothe mantle supports 14, and is burned as it is discharged into themantles.

From the foregoing, it is thought that the construction, operation andmany advan tages of the herein described invention will be apparent tothose skilled in the art, with out further description, and it will beunderstood that various changes in the size, shape, proportion and minordetails of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a lamp, the combination with a vertical downwardly extendingvaporizing tube, of a combined cutoff valve and gas regulator at thelower end of the tube, a depending feeding nozzle carried by the lowerend of the valve in substantial alinement with the vaporizing tube, airmixing means suspended from and inclosing the nozzle, and a mantlesupport carried by the upper portion of the mixing means and located atone side of the same.

2. In a lamp, the combination with a vertical downwardly extendingvaporizing tube, of a combined cutofi valve and gas regulator at thelower end of the tube, a depending feeding nozzle carried by the lowerend of the valve in substantial alinement with the vaporizing tube, amixing chamber body located below and in alinement with the vaporizingtube, mantle supports carried by the upper end of the body, and acombined air and vapor conducting tube depending within the body andhaving an inlet at its upper end, said tube also having1 the nozzledelivering into said upper en 3. In a lamp, the combination with avertical downwardly extending vaporizing tube, of a combined cutoff andvapor regulating valve carried. by its lower end, a depending vaporfeeding nozzle suspended from the lower end of the valve in line withthe vaporizing tube, a vertical combined vapor and air conducting pipedisposed in line with the vaporizing tube and nozzle and having thelatter extending into its upper In testimony whereof I affix mysignaend, said pipe having an offset air inlet, ture in presence of tWoWitnesses. a mixing chamber surroundin the tube and offset dependingmantle supp drts exten ding YVILLIAM COLEMAN outwardly from the upperend of the mix- Witnesses:
